Qinglang Miao 136ce7684b drm: rcar-du: Fix PM reference leak in rcar_cmm_enable()
pm_runtime_get_sync will increment pm usage counter even it failed.
Forgetting to putting operation will result in a reference leak here.

A new function pm_runtime_resume_and_get is introduced in [0] to keep
usage counter balanced. So We fix the reference leak by replacing it
with new funtion.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
